MOBILE, Alabama -- Dmitriy Salinta recorded a convincing victory over Roberto Valenzuela in a junior middleweight fight that was an undercard bout on Saturday night of the Deontay Wilder-Kerston Manswell heavyweight main event at the Mobile Civic Center's Expo Hall.

The referee stopped the bout in the fourth round when Salinta recorded punch after punch to Valenzuela, who had no defense.

Salinta, now 34-1-1 with 17 knockouts, pummeled Valenzuela throughout the fight with vicious left hooks to the body, including one that dropped Valenzuela to his knees in front of his corner at the end of the third round.

Salinta continued his assault in the fourth round, again getting Valenzuela in his own corner and landing shot after shot until the referee stopped the fight.

It was the 104th professional fight of Valenzuela's career. His record is now 39-63-2.

"He had more fights than I did in amateur and pro put together," Salinta said. "It was a good experience. It was my first time in Mobile, Alabama, and it seemed like the crowd liked me, so it's something I can add to me checklist. ... I've kind of been a good body puncher my whole career. He was taller than me and when a guy is taller than you, you kind of want to break him down with body shots.

"He was swinging wild and I didn't want to go back because he was swinging wild and I didn't want to give him the opportunity to head-butt. I just tried to keep the pressure on him and I broke him down."
